Plot summary

Join Alvin and his brothers Simon and Theodore for this hilarious Halloween adventure. Alvin wants to be accepted into the Monster Club, but the Monster members seem to think its cool to be cruel. It takes Theodore's friendship to Michael, a misunderstood outcast the other kids call Pumpkinhead, to show Alvin that being a true friend is really a lot more cool than trying to be a popular Monster! There are plenty of laughs and surprises and music, including the Chipmunk's rendition of the hit song "Monster Mash" to make this a monstrously fun video any time of the year!
